All Flashcards
What is the effect of moving a charge along an equipotential line?
No work is done, and the electric potential energy remains constant.
What happens to the electric potential (V) as the distance (r) from a point charge approaches infinity?
The electric potential (V) approaches 0.
What is the effect of doing work by the electric field on a charge?
The electric potential energy of the charge decreases.
What is the effect of doing work against the electric field on a charge?
The electric potential energy of the charge increases.
What is the key difference between electric potential energy () and electric potential (V)?
is the energy in Joules, while is the energy per unit charge in Volts (J/C).
Compare and contrast electric field lines and equipotential lines.
Electric field lines indicate the direction of the electric field, while equipotential lines connect points of equal electric potential. They are always perpendicular to each other.
Define electric potential energy ().
The energy a charge possesses due to its position in an electric field.
Define electric potential (V).
Electric potential energy per unit charge. It represents the 'push' available to move a charge.
Define equipotential lines.
Lines or surfaces where the electric potential is constant. No work is done moving a charge along these lines.
What are Volts (V)?
The units for electric potential, equivalent to Joules per Coulomb (J/C).
Define Work in the context of electric forces.
Work is done when moving charges in an electric field, overcoming the electric force.
